Abstract (en)
[origin: US2019038484A1] A system and method for improving stability of a wheelchair user includes a wheelchair having sensors measuring motion parameters to sense collisions and sharp turns which may unseat the user. Neuromuscular stimulating electrodes attached to extensor and flexor muscles of the user's trunk and under the command of a controller in communication with the sensors activate the muscles during turns and collisions to counteract the forces induced. A system and method for increasing manual propulsion efficiency includes sensors for sensing motion parameters indicating completion of a manual push of the wheelchair wheels and recovery from the push. Neuromuscular stimulating electrodes attached to extensor and flexor muscles of the user's trunk and under the command of a controller in communication with the sensors activate the muscles at the appropriate time in the cycle of push and recovery.
